我如何在 Angular2 应用程序中 embed/isolate JS 组件（Google 地图）？

Question

在尝试将 Google 地图 (API v3) 小部件嵌入 Angular2 应用程序时，我发现有一个 click/drag 错误困扰着我。

我想知道是否有一种好方法可以嵌入与 Angular 隔离的 Google 地图组件。根据堆栈跟踪（如下），在 Zone 尝试调用任务后，Google Maps 似乎出现了意外情况。

简单的 Plunkr 示例（可运行）：https://plnkr.co/edit/Tg3zwphygrgLUG5mq8Cc

每次错误点击后回溯（README.md）：

Angular2 基本应用程序 (main.ts)

import {bootstrap}    from 'angular2/platform/browser';
import {Component} from 'angular2/core';

// Create Angular component
@Component({
    selector: 'my-app',
    template: '<h1>My First Angular 2 App</h1>'
})
export class AppComponent { }

// Bootstrap the component
bootstrap(AppComponent);

观察：

每次点击都会触发错误
错误似乎并不严重，但最好不要在摇摇欲坠的基础上继续

很少有 3rdparty 解决方案提供像 https://angular-maps.com/ 这样随时可用的组件。
